Products/Services for Photoelastic Modulator

Acousto-optic modulators are devices that use sound waves to modify the amplitude, frequency, or phase of light passing through an acousto-optic material. For materials with a fixed acoustic velocity, the acoustic wavelength is a function...

Quadrature phase shift keying (QPSK) modulators and binary phase shift keying (BPSK) modulators are used to change certain characteristics (amplitude, frequency or phase) of a carrier signal in order to transmit information. The changes...

Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself...

I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information. I/Q modulators split an incoming data stream into its in-phase (I) and quadrature (Q) components, mix the resulting...

RF transceivers are electronic devices that receive and demodulate an RF signal, then modulate and transmit a new signal. RF transceivers are electronic devices that receive and demodulate radio frequency (RF) signals, and then modulate and transmit...

RF transmitters are electronic devices consisting of an oscillator, modulator, and other circuits that produce an RF signal. An RF transmitter is a device that creates a radio signal containing information that with the use of an antenna propagates...

Cellular modems are special types of modem used to modulate analog signals, such as telephone signals, to be transmitted using cellular networks. The modulated signal is used for phone or data communication with smart phones and similar device...

...signal rectifiers, oscillators and signal modulators / demodulators. A semiconductor diode is a non-linear device whose most outstanding feature is the fact that, basically, current is only allowed to flow in one direction. The diode is built...

Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given volume than linear amplifiers. They are also less expensive. Pulse width...

Electro Optical Components, Inc.Spatial Light Modulator
These spatial light modulators are extremely powerful new optical devices which individually manipulate each pixel in real-time. Not only is it possible to directly connect PC video/graphics to RL-SLMs in the same way as plug-and-play projectors, but users can also program these dynamic optical elements to behave like gratings, lenses, diffractive optical elements, apertures, masks, information processors & encryptors. RealLight's spatial light modulators are truly revolutionary devices whose...
